GAGE AND MARKER.

SPECIFICATION forming part of Letters Patent N0. 757,132, dated April12, 1904.

Application filed December 2, 1903.

To on whom it may concern:

Be it known that I, WILLIAM EMoRrLoUeH, a citizen of the United Statesof America, residing at Farmington, in the county of Marion and State ofWest Virginia, have invented certain new and useful Improvements inGages and Markers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention has relation to gages and markers for settingmortise-locks, and has for its object the provision of means foraccurately marking upon the edge of a door the upper and lower lines ofthe mortisefor the face-plate of the lock and for simultaneously markingthe position of the keyhole and the hole for the knob-bolt.

In carrying my invention into effect Iprovide a gage which is adapted tofit against and embrace the edge and part of the side of a door andwhich gage is provided with adju'stable marking devices by means ofwhich the gage is adapted to be used in conjunction with mortise-locksof different sizes, so that whatever may be the size of the lock or itsface-plate and the position of its keyhole and bolt-hole the gage can beadjusted to accurately mark the upper and lower lines of the mortisewhich is to be cut for the reception of the face-plate and also adjustedto accurately mark the centers for the keyhole and bolt-hole which areto be bored in the door.

My invention consists in the provision of a gage of novel form andconstruction having means formarking on a door the points at which thedoor is to be cut away and bored for the reception of a lock; and myinvention further consists in the novel constructions, combinations, andarrangements of parts hereinafter described.

In the accompanying drawings, in which like reference-letters designatecorresponding parts in the several figures, Figure 1 is a perspectiveview of my improved gage, a mortise-lock, and part. of a door to whichthe gage and lock are applied in operative position. Fig. 2 is a similarView of part of a door, showing the marks made by the gage to indicatethe positions of the mortise for the face-plate and the keyhole andbolt-hole.

$erial. No. 183,473. (No model.)

Fig. 3 is a perspective View looking at the gage from one point of View.Fig. 4: is a similar view showing the opposite side to that shown inFig. 3. Fig. '5 is a sectional view of that part of the gage which marksthe position of the bolt-hole. Fig. 6 is a sectional detail view of partof the gage and the adjustable marker for the upper edge of the mortise.

A designates the edge of the door, and B theface thereof.

The gage and marker, which is shown applied to the edge of the door inFig. 1, is composed of a flat plate O, of suitable length and width, ator about the center of which and at right angles thereto is fixedanother plate, D, of the same lengthas plate (1. The inner edge of plateDnext to plate C is cut away. as

shown at d in Figs. 3 and 4, for the reception of the edge of theface-plate of the look, as will be hereinafter described. Two parallelslots 0 c are cut through the plate C near its upper end, and a movableplate E is arranged on the front of plate C over the 'slots 0 c, andrivets e c are fixed in the plate E and passing through the slot 0 serveto attach to said plate E a plate F, which is bent at right angles, onearm, 6, of said plate F bearing against the back of plate 0, while theother arm, f, bears against the side of the plate D. The arm f of plateF is formed with a slot f through which passes a threaded stud g,carrying a thumb-nut G, by means of which said plate F is fixed in anyposition to which it may be adjusted. A marking-pin 0, carried by plateE, projects through the slot 0 and serves to mark the position of theupper edge of the mortise for the face of the lock. Near the bottom andupon the inner side of plate C an angle-plate H is fixed, the uppersurface of said plate being on a line with the lower end of the slot onthe inner edge of plate D, and a marking-pin h is fixed in the back ofplate 0 on a line with the lower edge of said slot, this pin serving tomark the point for the lower line of the mortise of the face-plate ofthe lock.

At a point about midway of the plate D a link I is pivoted at one end toplate D and at the other end is pivoted to a link K, which is slotted atis for the passage of a square bolt L, means of which link K ispivotally attached to a link M, which is slotted at m for the passage ofsaid bolt L and carries at its lower end a pin N, which has its innerend sharpened, as shown at n, said sharpened end constituting amarking-pin for the keyhole. The inner end of the bolt L is sharpened,as shown at Z, and said sharpened point forms a marking-pin for thebolt-hole of the lock, and the said bolt is held in position in thelinks K and M, and the said links are pivotally attached on said bolt bymeans of a washer O, attached to the bolt by screwing it thereon,soldering it thereto, or afiixing it in any other suitable manner insidethe point Z of the same. In operation the lock which is to be put on thedoor is applied to the'gage in the following manner: The links KM areadjusted one onthe other until the bolt L and the pin N coincide to theposition of the bolt-hole and the circular portion of the keyhole of thelock. The bolt L is then inserted in the bolt-hole and the pin N in thekeyhole, and the faceplate of the lock is brought up against the back ofplate C, the edge of the face-plate being pushed into the slot cl at therear of plate D, the lower edge of the face-plate resting on the blockH. The plates E and F are now adjusted until the lower edge of arm f ofplate F rests upon the upper edge of the face-plate. The gage, with thelock attached, as above described, is then applied to the door, as shownin Fig 1, and the pins 6 and h on the plate C are pressed into the edgeA of the door, and the pins on the inner ends of bolt L and pin N arepressed into the side of the door, leaving marks or indentations e, h,Z, and n, which, as-shown in Fig; 2, indicate the upper and lower edgesof the face-plate and the centers for the bolt-hole and keyhole.

The device described provides a simple and eflicient means forexpeditiously and accurately marking the points at which the door is tobe mortised and bored and obviates the slow and uncertain method ofdetermining these points heretofore practiced.

marking-point adapted to indicate on the edge e of adoor the upper andlower edges of the mortise and having adjustable marking-points arrangedat right angles to said first-named marking-points and adapted toindicate on the side of the door the positions of the keyhole andknob-hole.

3. A gage and marker for marking doors, comprising a plate adapted torest against the edge of the door, marking-points on said plate toindicate the position of the mortise of a lock, pivoted links attachedto said plate, a bolt adapted to enter the bolt-hole of a lock, amarking-point on the inner end of said bolt, a pin adapted to enter thekeyhole of the lock and a marking-point on the inner end of said pin.

a. A gage and marker for marking doors comprising a plate adapted to beapplied to the edge of the door, marking-points on said plate, a platesecured at right angles to the first-named plate and adapted to beapplied to the side of the door and having a slot for the reception ofthe face-plate, of a lock, a bolt and a pin having marking-points,adjustable links upon which the bolt and pin are carriedand a linkconnecting one of said adjustable links to the said slotted plate.

In testimony whereof Iaflix my signature'in the presence of twowitnesses.
